Arguments

data

a vector of edge values with 4005, 7021, 23871 or 30135 columns

surf_color

alpha value of the cortical surface, where 0 will cause the cortical surface to disappear and 1 will cause the cortical surface to be completely opaque. Set to 0.2 by default

node_color

color of the nodes. Set to '#00BA38' by default

cmap

A string vector containing 2 to 3 color names/codes specifying the colors to be used for the color scale. If none are specified, appropriate colors will be automatically selected according to range(surf_data)

node_size

size parameter for the dots representing the nodes. Set to 8 by default.

edgethickness

a value to adjust the thickness of the edges. Set to 8 by default.

limits

A combined pair of numeric vector composed of the lower and upper color scale limits of the plot. When left unspecified, the symmetrical limits c(-max(abs(surf_dat),max(abs(surf_dat))) will be used.

colorbar_title

title for the colorbar legend. Set to 'Connectivity strength by default

orientation_labels

A boolean object specifying if orientation labels are to be displayed. Set to TRUE by default

remove_brain

A boolean object specifying cortical surface should be removed. Set to FALSE by default

Value

outputs a plot_ly object

Details

This function takes a vector (length(data)=number of edges in the connectome) of edge values and visualizes the edge-to-edge connectivity with a glass brain plot

Examples

mask=sample(c(1,0), 7021, replace = TRUE, prob = c(0.001, 0.999))
data=runif(7021,min = -1,max=1)*mask
